weird neighborhoos sound
When I sit in my garage in the evening and indulge in a cigar and perhaps an adult beverage, I ofetn hear a sound somewhat off in the distance but still in my area. It's a pinging of some sort, actually it sounds exactly like one of those submarine sonar pings like a 1950's movie sound effect.
I've ruled out a lot...it's not a traffic signal aid for the blind, for instance which was my main guess.
How would you go about trying to figure it out without, err, looking like the crazy person on the block?
It's mostly a source of amusement for me...not like I've been dipping into the koolaid or wearing foil helmets...:)
